摘要：

Hydrothermal crystallization in the systems Nd2O3(Nd(NO3)3 ⋅ 6H2O)-CaCO3(BaCO3)-R-H2O (R = Na2CO3, K2CO3, NaCl, NH4Cl, NaHCO3, KHCO3, Na2CO3 + NaCl, Na2CO3 + NH4Cl, Na2CO3 + CO(NH2)2) was studied in the range 400–480°C. All of the precipitates were found to contain crystalline NdOHCO3, NaNd(CO3)2, and Nd2(OH)4CO3. The lattice parameters of NdOHCO3 were refined, and a detailed scheme for its thermal decomposition was proposed.
